Definitions

  • the present invention relates to the field of communications technologies, and in particular, to a status detection method and a wireless network node.
  • a network node such as a base station or a controller needs to determine the peer end network status.
  • a service address pair status is regularly detected by pinging, so that a wireless network node in the network obtains a peer end network status.
  • a service address pair status is regularly detected by using a packet data packet encapsulation (GPRS Tunneling Protocol User Plane, GTPU) response, so that a wireless network node in the network obtains a peer end network status.
  • GPRS Tunneling Protocol User Plane GPRS Tunneling Protocol User Plane
  • a packet needs to be sent periodically regardless of whether pinging or a periodic heartbeat (GTPU response) is used. If a radio network controller (Radio Network Controller, RNC) is connected to tens of hundreds of base stations, or LTE is connected to a large quantity of S1 or X2 interfaces, consumption of both a central processing unit (Central Processing Unit, CPU) and network traffic is high, and scalability of such detection is extremely poor.
  • RNC Radio Network Controller
  • This application provides a status detection method and a wireless network node, to greatly reduce traffic consumption between networks, reduce load on a network device, and improve detection efficiency.
  • a first aspect of this application provides a wireless network node, applied to user plane service address pair status detection, where the wireless network node includes:
  • the sending unit is further configured to: when it is determined that the target network node is online at a current moment, if the normal data packet sent by the target network node is not received after the second preset time interval, send a probe packet to the target network node; and the determining unit is further configured to: when a second response message returned by the target wireless network node is received, determine that the status of the target network node is online.
  • the sending unit is further configured to resend the probe packet if the first response message returned by the target wireless network node is not received at a third preset moment; and the determining unit is configured to: if a response message returned by the target wireless network node is still not received when the sending unit sends the probe packet for an N th time, determine that the status of the target network node is offline, where N>1 and N is a positive integer.
  • a second aspect of this application provides a wireless network node, applied to user plane service address pair status detection, where the wireless network node includes:
  • the wireless network node further includes:
  • a third aspect of this application provides a status detection method, applied to user plane service address pair status detection, where the method includes:
  • the method further includes:
  • the method further includes: resending, by the first wireless network node, the probe packet if the first wireless network node does not receive, at a third preset moment, the first response message returned by the second wireless network node, and if a response message returned by the second wireless network node is still not received when the probe packet is sent for an N th time, determining that the status of the second wireless network node if offline, where N>1 and N is a positive integer.
  • a fourth aspect of this application provides a status detection method, applied to user plane service address pair status detection, where the method includes:
  • the method further includes:
  • a wireless network node that needs to know a peer end network status sends a probe packet to a peer end to determine whether the peer end is online.
  • a quantity of service packets for peer end status detection is minimized by using traffic of the packets, thereby greatly reducing traffic consumption between networks, reducing load on a network device, and improving detection efficiency.
  • This application provides a status detection method and a wireless network node, to greatly reduce traffic consumption between networks, reduce load on a network device, and improve detection efficiency.
  • the wireless network node 100 includes: a judging unit 101, a determining unit 102, and a sending unit 103.
  • the judging unit 101 is configured to determine whether a normal data packet sent by a target wireless network node is received within a first preset time interval.
  • the normal data packet may be a GTPU response request packet, for example, a GTPU Echo Req packet, or may be a normal User Datagram Protocol (User Datagram Protocol, UDP) data packet sent by the target wireless network node to the wireless network node, or the like. This is not limited herein.
  • UDP User Datagram Protocol
  • the determining unit 102 is configured to: when the judging unit 101 determines that the normal data packet sent by the target wireless network node is received within the first preset time interval, determine that a status of the target network node is online, where when the status of the target network node is online, no probe packet needs to be sent to the target wireless network node.
  • the sending unit 103 is configured to send a probe packet to the target wireless network node when the judging unit 101 determines that the normal data packet sent by the target wireless network node is not received within the first preset time interval.
  • the determining unit 102 is further configured to: when a first response message returned by the target wireless network node is received, determine that the status of the target network node is online.
  • the judging unit 101 determines whether the normal data packet sent by the target wireless network node is received within the first preset time interval.

  • the sending unit 103 sends the probe packet to the target wireless network node when the judging unit 101 determines that the normal data packet sent by the target wireless network node is not received within the first preset time interval.
  • the determining unit 102 is further configured to: when the first response message returned by the target wireless network node is received, determine that the status of the target network node is online. According to this application, traffic consumption for status detection between two wireless network nodes is greatly reduced, load on a network device is reduced, and status detection efficiency is improved.
  • the sending unit 103 is further configured to: when it is determined that the target network node is online at a current moment, if the normal data packet sent by the target network node is not received after the second preset time interval, send a probe packet to the target network node; and the determining unit 102 is further configured to: when a second response message returned by the target wireless network node is received, determine that the status of the target network node is online.
  • the sending unit 103 is further configured to resend the probe packet if the first response message returned by the target wireless network node is not received at a third preset moment; and the determining unit 102 is configured to: if a response message returned by the target wireless network node is still not received when the sending unit 103 sends the probe packet for an N th time, determine that the status of the target network node is offline, where N>1 and N is a positive integer.
  • the first wireless network node may be a base station or a radio network controller RNC.
  • the second wireless network node is a base station or an RNC.
  • a wireless network node determines that another wireless network node is online means that the wireless network node determines that the wireless network node and the another wireless network node are connected and may exchange information. If the wireless network node determines that the wireless network node and the another wireless network node are not connected, the wireless network node determines that the another wireless network node is offline.
  • the following describes a wireless network device status detection procedure with reference to a specific application scenario.
  • the hello message may be a User Datagram Protocol (User Datagram Protocol, UDP) ping packet.
  • UDP User Datagram Protocol
  • a receives a hello message sent by B within a first preset time interval (for example, 10s) A determines that B is online. If A does not receive any hello message within the preset time interval, A proactively sends a hello message to B, and if B returns an acknowledgment response message (ACK message) to A, A determines that B is online.
  • the ACK message may be an Internet Control Message Protocol (Internet Control Message Protocol, ICMP) ping packet. As shown in FIG.
  • A resends the hello message. If B still does not return any ACK message when A sends the hello message for an N th time, A determines that B is offline.
